Abstract:
Objective To study the clinicopathologic features and prognosis factor of Chinese lymphoblastic lymphoma.Methods 105 LBL cases were collected.Routine HE staining,immunostaining were used to investigate the clinicopathologic features,immunotype.Results The ratio of male to female was 1.76:1 (67:38),the medial age was 13 years old (0-73 years old).53 cases (53/105,50.48 ％) primarily showed lymph node involvement,including 34 cases (34/53,64.15 ％) showed jugular node involvement;mediastinum (12/52,23.08 ％) was the most frequent extranodal involvement site.69 cases (69/105,65.71％)showed bone marrow involvement with 15 cases as the primary involvement.The expression of TdT,CD99,CD3(E),CD20,CD79a,PAX5,MPO,CD34 and CD117 was 84.76 ％ (89/105),85.00 ％ (68/80),54.37 ％ (56/103),16.67 ％ (16/96),40.00 ％ (8/20),46.67 ％ (28/60),14.29 ％ (8/56),25.00 ％ (4/16) and 0.All cases were divided in to two groups,62 cases as T-LBL (59.05 ％,62/105) and 33 cases as B-LBL (31.43 ％,33/105),with 9 cases (8.57 ％,9/105) without the expression of T or B cell marker and 1 cases with the expression of both T and B cell marker.61 cases were detected the expression of myeloid markers and 8 cases were positive.All cases were followed up.The medial survival was 36 months.The survival at 1 year,2 year and 3 year was 66.67 ％ (70/105),48.81％ (41/84) and 20.69 ％ (12/58) respectively.Age was the prognosis associated factor.The children had better progonosis than adults.Immunotype,bone marrow involovement and transplantation didn' t show prognosis indicator (P ＞ 0.05).Conclusion Most of Chinese LBL occurs in child and younger male,multi-lymphadehypertrophy and bone marrow involvement are common.LBL is an aggressive tumor.Age is the prognosis associated factor.Children have a better prognosis than the adult.
